Abstract

The system has a computer (3) connected with a data storage unit (4), an engine speed determining unit (5) and an engine temperature measuring unit (6). The computer controls electric supply of an electric oil pump (1) by pulse width modulation according to the rotation speed of the engine and temperature of the engine.

Description

La présente invention concerne un système de commande du fonctionnement d'une pompe électrique d'huile de lubrification d'un moteur à deux temps de véhicule à deux roues de type scooter.
On sait que les véhicules de ce type et plus particulièrement leur moteur à deux temps, sont associés à des pompes électriques d'huile de lubrification de ceux-ci pour assurer leur graissage.
Ces pompes sont généralement activées à plein régime sous pleine tension pour assurer une lubrification suffisante du moteur quelles que soient les conditions de roulage du véhicule.
On conçoit cependant que cette lubrification n'est alors pas optimisée.
Le but de l'invention est donc de résoudre ces problèmes.
A cet effet, l'invention a pour objet un système de commande du fonctionnement d'une pompe électrique d'huile de lubrification d'un moteur à deux temps de véhicule à deux roues de type scooter, caractérisé en ce qu'il comporte des moyens de régulation de l'alimentation électrique de la pompe en fonction du régime de rotation du moteur.
Suivant d'autres caractéristiques de l'invention : - les moyens de régulation comprennent un calculateur associé à des moyens de stockage de données et raccordé en entrée à des moyens de détermination du régime de rotation du moteur ; - le calculateur est également raccordé en entrée à des moyens de mesure de la température du moteur ; - l'alimentation de la pompe est régulée en largeur d'impulsions ; et - le calculateur est le calculateur de tableau de bord du véhicule.
L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant au dessin annexé, qui représente un schéma synoptique illustrant la structure et le fonctionnement d'un système de commande selon l'invention.
On a effet illustré sur cette figure, un système de commande du fonctionnement d'une pompe électrique d'huile de lubrification d'un moteur à deux temps de véhicule à deux roues de type scooter par exemple.
Cette pompe est désignée par la référence générale 1 sur cette figure et est associée à des moyens de régulation de son alimentation désignés par la référence générale 2.
Ces moyens de régulation comprennent par exemple un calculateur désigné par la référence générale 3 et associé à des moyens de stockage de données désignés par la référence générale 4. Ce calculateur est raccordé en entrée à des moyens de détermination du régime de rotation du moteur du véhicule désignés par la référence générale 5.
En fait, ce calculateur est de préférence un calculateur de gestion du tableau de bord du véhicule.
Ce calculateur peut également être associé en entrée à des moyens 6 de mesure de la température de fonctionnement du moteur du véhicule.
Ces paramètres d'entrée permettent alors au calculateur 3, de réguler, par l'intermédiaire d'un étage de sortie de puissance, l'alimentation électrique de la pompe en fonction du régime de rotation du moteur du véhicule et éventuellement de sa température, afin d'optimiser cette commande et donc la lubrification du moteur, pour les conditions réelles de fonctionnement de ce moteur.
Ceci permet alors d'ajuster la lubrification du moteur du véhicule à ces conditions de fonctionnement.
La régulation de la commande de la pompe électrique peut exemple être assurée en modulation de largeur d'impulsions ou autre.
Bien entendu, d'autres modes de réalisation peuvent être envisagés.
Ainsi par exemple, le régime de rotation du moteur peut être mesuré directement ou déduit de la vitesse de déplacement du véhicule.The present invention relates to a system for controlling the operation of an electric lubricating oil pump of a two-stroke scooter-type two-stroke motor vehicle.
It is known that vehicles of this type and more particularly their two-stroke engine, are associated with electric pumps lubricating oil thereof to ensure their lubrication.
These pumps are generally activated at full speed under full voltage to ensure adequate lubrication of the engine whatever the driving conditions of the vehicle.
However, it is understood that this lubrication is not optimized.
The object of the invention is therefore to solve these problems.
To this end, the subject of the invention is a system for controlling the operation of an electric lubricating oil pump of a two-stroke scooter-type two-wheeled vehicle, characterized in that it comprises means for regulating the power supply of the pump as a function of the rotational speed of the motor.
According to other features of the invention: the regulation means comprise a computer associated with data storage means and connected at input to means for determining the rotational speed of the engine; the computer is also connected as input to means for measuring the temperature of the motor; the power supply of the pump is regulated in pulse width; and the computer is the vehicle dashboard computer.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawing, which represents a block diagram illustrating the structure and operation of a control system according to the invention.
This figure shows a control system of the operation of an electric lubricating oil pump of a two-cycle motor of a two-wheeled vehicle such as a scooter.
This pump is designated by the general reference 1 in this figure and is associated with means of regulating its supply designated by the general reference 2.
These control means comprise, for example, a computer designated by the general reference 3 and associated with data storage means designated by the general reference 4. This computer is connected as input to means for determining the rotational speed of the vehicle engine. designated by general reference 5.
In fact, this computer is preferably a management computer of the vehicle dashboard.
This calculator can also be input associated with means 6 for measuring the operating temperature of the vehicle engine.
These input parameters then allow the computer 3 to regulate, via a power output stage, the power supply of the pump as a function of the rotation speed of the vehicle engine and, if appropriate, its temperature. in order to optimize this control and therefore the lubrication of the engine, for the actual operating conditions of this engine.
This then makes it possible to adjust the lubrication of the engine of the vehicle to these operating conditions.
The control of the control of the electric pump can for example be provided in pulse width modulation or the like.
Of course, other embodiments can be envisaged.
For example, the rotational speed of the engine can be measured directly or deduced from the speed of movement of the vehicle.
